Abstract (en)

When an ignition key is switched off (in S310), an updated learning value (updated in S308) is set as an immediately preceding learning value of a present trip, which is compared with an average value of start timing learning values in a predetermined number of trips up to and including the present trip. When a difference between the immediately preceding learning value of the present trip and the average value exceeds a predetermined range, a start timing learning value to be used at a startup of a next trip is not updated. When the difference between the immediately preceding learning value of the present trip and the average value falls within the predetermined range, the immediately preceding learning value of the present trip is written in an EEPROM (in S314) and used as the start timing learning value at the engine startup of the next trip.
